Hi All, I have downloaded an extension for PostgreSql. It contains stored procedures written in C. I compiled the neccessary files into an so file and I tried to use the functions, but it gives an error message when it has to load the shared object file. The error message says, it cannot locate a symbol. I think this symbol is part of the C++ STL. This is the error message: psql:/usr/share/postgresql/contrib/proximity.sql:5: ERROR: could not load library "/usr/lib/postgresql/proximity.so": /usr/lib/postgresql/proximity.so: undefined symbol: _ZNKSs17find_first_not_ofERKSsj What should I do to be able to use this extension? Anyone has any experience with this extension?
